LOCKING DEVICE FOR CAR-DOORS.

Speciiication of Letters Patent.

Application filed October 18, 1915. Serial No. 56,550.

'A T0 all whom t may concern installed can be easily operated tovrelease or Be it known that I, HENRY HAMILTON BREWER, of the city ofWinnipeg, in the Province of Manitoba, Canada, have invented certain newand useful Improvements in Locking Devices for Car-Doors, of which thefollowing is the specification.

The invention relates to improvements in locking devices for car doorsand the object of the invention is to provide an ineX- pensive lockingdevice which can be manufactured at small cost and can be easily andquickly applied on the car and which when positively fasten the. door.

A further object of the invention is to4 construct the device with asfew parts as l possible and in a manner such that it can be readilyassembled and can be iitted on all eX- isting types of doors withoutrequiring any changes in the door'structure.

With the above objects in View the invention consists essentially in atwo-piece or split bearing sleeve having one end formed to present atwo-piece face plate,'a locking bolt mounted in the sleeve and fittedIwith ahand lever, a clamping Thead located at'the inner end of the bolt,a guide flange extending from the plate behind the lever, a receivingretaining plate' for the head, means for fastening the retaining plateto the car, means for fastening the face plate to the door and a pinextending from the back face of the face plate into the door, the partsbeing arranged and constructed as hereinafterA more particularlydescribed and later pointed out in the appended claims, reference b einghad to the accompanying drawings in which Figure 1 represents a sideview of a'door fitted with my locking device. Fig. 2 represents anenlarged detailed vertical sectional view through the locking device asit appears in the locked position, the locking bolt being shown in sideelevation. Fig'. 3 is an enlarged front face view of the device.

Fig. l represents an enlarged perspective.

the second door post of the struction, being found on practicallyv alltypes ofcar doors.

According to present practice, the front edgev of the door is locked byfastening the hasp to the staple by any of the well known forms of carseals. With my invention applied, the-rear edge of the door is fastenedto the post and it is unnecessary to utilize the -hasp, staple and sealon the front edge of the door.

Referring again to the drawings; 12 is a sleeve formed from interiittingtop and bottom sleeve sections 18 and lll, which sleeve has the forwardend thereof presenting a two-piece or split face plate 15, the split inY the Vface plate* occurring at the joint between the sleeve members.

The sleeve section 12 is fitted with facial extensions 16 and iin sleevesection 14 are made receiving pockets 17 which prevent All theabove'parts are of ordinary con'` end movement of the .sleeve memberswhen the same are closed together.

The sleeve is applied on the door by boring a hole 18 in the lower righthand corner of the door to receive it', and in this connection it is tobe noticed that it only projects partially through the door, as bestshown.

in Fig. 2, thereby vreserving a receiving opening 19 in the doorimmediatelyy to the rear of the inserted sleeve.'

The face plate is fastened permanently to the door by bolts 20. and 21passing through the lower part of the face plate and into and throughthe door,-the heads of the bolts being countersunk in the face platewhile the nuts 22 on the rear ends of said bolts are countersunk in theback face of the door.

23 is a locking bolt passing through the sleeve and rotatably mounted inthe same, and having the outer end thereof formed linto a hand lever 24ypositioned at lright angles to the body of the bolt and the inner endthereof supplied .with a clamping T- head 25, said head having the innercorners thereof beveled off and the ends thereof rounded, as best shownin Fig. 4 of the drawings.

The head is set at right angles to the hand lever so that when the leveris in the vertical position the head is in the horizontal.

26k is a llange cast as part of the lower portion of the face plate 15.This'flange gradually increases in width throughout its length and by sodoing presents an inclined guiding face 27 on which the lever 24 isdesigned to operate in the turning thereof.

A stop 2S is formed as part of the flange, which stop limits theswinging of the lever in one direction.

Immediately behind the inserted sleeve, the front face of the post 9 iscut away as indicated at 29 to receive the head of the locking bolt, andthe opening so formed is guarded by a retaining plate 30 which isdesigned to admit the head 25 into the opening 29V when the head is inthe vertical position,`

but is arranged to prevent the withdrawal of the head from the openingupon the head being turned a quarter turn after insertion therein.

rlhe opening 19 is arranged to receive the head when the locking bolt,after being unf locked, is withdrawn fully outwardly.

In designing this locking device, it is necessary that the length of thelocking bolt be such that withthe head inserted behind the retainingplate andthe hand lever in the position on the flange shown in Fig. 4 ofthe drawings, the door be jammed tightly against the post. It is obviousthat as the lever is turned and climbs up the inclined face 27, the faceplate and door to which it is attached will be forced inwardly towardthe post. Conversely, as the lever is released, the door willbereleased.

In order to prevent the lock from being undone by removing the bolts 20and 21, I

have supplied a pointed stud 34 on the back face of the face plate,which pin is embedded in the face of the door and operates to preventthe face plate being rotated after the removal of the bolts. If itcannot rotate, the head cannot be released from the retaining plate. Y

With my invention applied on a car, all that is necessary to do is toclose the door in the usual way against the jam strip. The attendantthen has only to enter the T-head in the opening 29 and bring the leverto the horizontal position as shown. In turning it he effects thejamming of the door against the posts in the manner hereinbeforedescribed. After the car seal is applied the car is ready for shipment.

In considering a door tted with my invention, it will be seen that it isimpossible to pry the door open, as the usual hangers on the trackprevent the top of the door from being sprung outwardly, while myfastening, together with the pin 35, prevents the lower side of the doorfrom being pried away from the posts.

In instances where it is not convenient to apply the ordinary car sealto lock the lever, this can be accomplished by locking a padlock to theHange, the bolt of the padlock being inserted through one or other ofthe openings 38 and 39 provided. Y

Vhat I claim as my invention is In combination in a closure of the classdescribed having an operatnglever, a face plate, and means thereon forwithdrawing said lever; comprising a flange on said plate having acurved edge, said flange being curved upwardly toward one extremity, and

a stop provided on the other extremity.
